Embodiment 1
[0033] The steel cage manufacturing method of cast-in-situ pile of the present invention, the diameter of the steel cage of cast-in-situ pile is 600mm, and the length of cast-in-situ pile is 35m, comprises the following steps:
[0034] a. Prefabricate several steel bar positioning discs.
[0035] see now figure 1 , figure 1 It is a structural schematic diagram of a reinforcing bar positioning disk according to an embodiment of the present invention. As shown in the figure, the disc is a ring. According to the design and size of the reinforcement cage, use steel plate 2 with a thickness of 6 mm to make some reinforcement positioning discs, and evenly arrange a number of main reinforcement through holes 3 on the surface of the ring to penetrate the main reinforcement of the reinforcement cage. The diameter of the reinforcing bar positioning disc is 600mm.
[0036] b. Use steel bars to position the disc.
[0037] Provide a reinforcement cage manufacturing platform, on which,...

Abstract
The invention discloses a reinforcement cage manufacturing method for cast-in-place piles; and the cast-in-place piles are 35 m long. The method is characterized by comprising the following steps: (a)multiple reinforcement positioning discs are prefabricated; (b) the reinforcement positioning discs are used; (c) reinforcing rib rings are added; and main rib fixing discs are removed; (d) spiral stirrup positioning buckles are manufactured and used; (e) gaps of the spiral stirrup buckles are arranged in a spiral stirrup compacting area away from the top end of a reinforcement cage by 3000 mm according to design requirements; and (f) two adjacent sets of spiral stirrup buckles are uniformly arranged in a spiral stirrup non-compacting area outside the spiral stirrup compacting area at intervals of 250 mm. The method has the advantages of simple structure and convenience for manufacturing of reinforcement positioning discs, guarantee of uniform intervals of spiral stirrups in the compacting area and the non-compacting area, accordance with the design requirements, increment of the once acceptation pass percent in reinforcement cage machining, prevention of rework caused by unqualifiedreinforcement cage acceptation and material and time waste caused by repeated work, and reduction of the labor and construction costs.
Description
technical field [0001] The invention relates to a method for manufacturing a reinforcement cage, in particular to a method for manufacturing a reinforcement cage for cast-in-situ piles. Background technique [0002] Caofeidian Comprehensive Free Trade Zone Innovation and Entrepreneurship Center Project, 5# and 6# apartment buildings use mud retaining wall bored piles with a diameter of 600mm, including 697 piles with a pile length of 35m and 196 piles with a pile length of 18.5m. The number of cast-in-situ piles is large, and it is difficult to control the spacing of the main reinforcement and the spacing of the spiral stirrup in the process of making the reinforcement cage. [0003] Therefore there are above-mentioned inconveniences and problems in the known steel cage manufacturing method. Contents of the invention [0004] The purpose of the present invention is to propose a safe and reliable steel cage manufacturing method for cast-in-place piles. [0005] For realiz...
